Development of a scrotal vasocutaneous fistula producing viable spermatozoa 9 years after vasectomy.

Objective: To describe a case of scrotal vasocutaneous fistula discharging viable sperm.

Design: Case report.

Setting: A hospital-based assisted conception center.

Patient(s): A 37-year-old male presenting for fertility treatment 9 years after vasectomy with a scrotal vasocutaneous fistula that caused a painful, intermittently rupturing, subcutaneous cyst.

Intervention(s): Analysis of fistula discharge and planned fistula resection with vasovasostomy.

Main Outcome Measure(s): Diagnostic semen analysis to determine presence or absence of spermatozoa in fistula discharge.

Result(s): A very low concentration of live spermatozoa were identified in the fistula discharge.

Conclusions(s): We believe this is the first time that live spermatozoa, potentially suitable for assisted conception treatment using intracytoplasmic sperm injection have been identified in the discharge from a vasocutaneous fistula.
